Bug Description

The root cause is a missing dependency after installing the Xenial LTS Enablement stack. This is the fix:

    apt install libwayland-egl1-mesa-lts-xenial

If I add "--debug" in /usr/share/xsessions/gnome.desktop, I see the following in ~/.xsession-errors:

    gnome-session[12878]: DEBUG(+): GsmAutostartApp: starting gnome-shell.desktop: command=/usr/bin/gnome-shell startup-id=10d41f1f5c81914ec61471971137183000000128780000
    gnome-session[12878]: DEBUG(+): GsmAutostartApp: started pid:13121
    ...
    /usr/bin/gnome-shell: error while loading shared libraries: libwayland-egl.so.1: cannot open shared object file: No such file or directory
    gnome-session[12878]: DEBUG(+): GsmAutostartApp: (pid:13121) done (status:127)
    gnome-session[12878]: WARNING: App 'gnome-shell.desktop' exited with code 127

which shows that gnome-shell won't start because of a missing wayland library.
